1)下層處理外墻下層上出現的有礙粘結的因素及處理辦法。

1) primary processing factors of exterior wall base on the bond and hinder approach.

2)防污條、防污紙粘貼外墻對美觀要求較高，因此施工時應粘貼好防污條和防污紙（河南人事考試網首頁），但同時也不能使防污條上的粘膠浸入到密封膠中去。

2) anti fouling strip, anti fouling paper paste the external walls of the higher requirements, so the construction should be pasted with anti fouling and anti fouling paper, but also can not make the adhesive on the anti fouling strip immersed in the sealant.

3)底涂料施工底涂料起著承上啟下的作用，使界面與密封材料之間的粘結強度有所進步，因此應認真地涂刷底涂料。底涂料的施工環境如下：施工溫度不能太高，以免有機溶劑在施工前就揮發完了。施工界面的濕度不能太大，以免粘結困難。基面外觀不應結露。

3) primer primer construction plays a very important role to make the interface bond strength and sealing material between improved, and should therefore be carefully brushing primer. The construction environment of the bottom coating is as follows: the construction temperature can not be too high, so as to avoid the organic solvent before the construction of volatile. The construction interface of the humidity can not be too large, so as not to bond difficult. The base surface should not be dew.

4)嵌填密封材料確定涂料已經干燥，但未超過24h時便可開始嵌填密封材料。充填時，金屬幕墻、PC幕墻、各種外裝板、混凝土墻應從縱橫縫交叉處開始；施工時，槍嘴應從接縫底部開始，在外力作用下先讓接縫材料充滿槍嘴部位的接縫（豪沃A7駕駛室），漸漸向后退，每次退的時候都不能讓槍嘴露出在密封材料表面百度優化，以免氣泡混入其中。

4) the sealing material has been dried, but the sealing material can be started when the material is not more than 24h. When filling, metal curtain wall, curtain wall, all kinds of PC plate and concrete wall should be vertical and horizontal seam intersections; construction, from the bottom to the gun nozzle joint, under the action of external force let joint material full of gun nozzle parts of the joint, gradually backward, every time back will be able to let the gun mouth exposed in the outside sealing material, so as to avoid the mixing of air.
